Go Bindings for GLFW 3

ATTENTION: As of GLFW 3.1 we break API. See Changelog below.
See here for documentation.
You can help by submitting examples to go-gl/examples.

Remarks

Mingw64 users should rename glfw3dll.a to libglfw3dll.a.
In Windows and Linux, if you compile GLFW yourself, use -DBUILD_SHARED_LIBS=on with cmake in order to build the dynamic libraries.
Some functions -which are marked in the documentation- can be called only from the main thread. You need to use runtime.LockOSThread() to arrange that main() runs on main thread.
In OS X, you can install Go and GLFW via Homebrew.

$ brew install go
$ brew tap homebrew/versions
$ brew install --build-bottle --static glfw3
$ go get github.com/go-gl/glfw3

Example

package main

import (
	"runtime"

	glfw "github.com/go-gl/glfw3"
)

func init() {
	runtime.LockOSThread()
}

func main() {
	err := glfw.Init()
	if err != nil {
		panic(err)
	}
	defer glfw.Terminate()

	window, err := glfw.CreateWindow(640, 480, "Testing", nil, nil)
	if err != nil {
		panic(err)
	}

	window.MakeContextCurrent()

	for !window.ShouldClose() {
		// Do OpenGL stuff
		window.SwapBuffers()
		glfw.PollEvents()
	}
}

Changelog

SetErrorCallback This function is removed. The callback is now set internally. Functions return an error with corresponding code and description (do a type assertion to GlfwError for accessing the variables).
Init Returns an error instead of bool.
GetTime Returns an error.
GetCurrentContext No longer returns an error.
GetJoystickAxes No longer returns an error.
GetJoystickButtons No longer returns an error.
GetJoystickName No longer returns an error.
window.GetMonitor No longer returns an error.
window.GetAttribute Returns an error.
window.SetCharacterCallback Accepts rune instead of uint.
window.SetDropCallback added.
window.SetCharacterModsCallback added.
PostEmptyEvent added.
Native window and context handlers added.
Constant ApiUnavailable changed to APIUnavailable.
Constant ClientApi changed to ClientAPI.
Constant OpenglForwardCompatible changed to OpenGLForwardCompatible.
Constant OpenglDebugContext changed to OpenGLDebugContext.
Constant OpenglProfile changed to OpenGLProfile.
Constant SrgbCapable changed to SRGBCapable.
Constant OpenglApi changed to OpenGLAPI.
Constant OpenglEsApi changed to OpenGLESAPI.
Constant OpenglAnyProfile changed to OpenGLAnyProfile.
Constant OpenglCoreProfile changed to OpenGLCoreProfile.
Constant OpenglCompatProfile changed to OpenGLCompatProfile.
